The National Hurricane Center and Forecasting Hurricanes: 2017 Overview and 2018 Outlook
The National Hurricane Center and Forecasting Hurricanes: 2017 Overview and 2018 Outlook Updated August 23, 2018 Congressional Research Service https://crsreports.congress.gov R45264 NHC and Forecasting Hurricanes: 2017 Overview and 2018 Outlook Summary The National Hurricane Center (NHC), part of the National Oceanic and Atmospheric Administration’s (NOAA’s) National Weather Service (NWS), is responsible for forecasting hurricanes in the Atlantic Ocean and the eastern Pacific Ocean. The NHC provides estimates of the path of a storm (i.e., hurricane track), the intensity, and the size and structure of the storm, as well as predictions of storm surge, rainfall, and even tornadoes. Depending on the storm’s status, this information may be used to create a hurricane watch or a hurricane warning and public advisories, which are issued on an increasingly frequent basis if a storm strengthens and approaches the U.S. coastline. Three major hurricanes struck the continental United States, the U.S. Virgin Islands, and Puerto Rico in 2017, causing severe damage: Harvey, Irma, and Maria. Hurricane Harvey was the first major hurricane to strike the continental U.S. coast since 2005, achieving category 4 strength before making landfall along the Texas coast on August 25, 2017. According to the NHC, Harvey “was the most significant tropical cyclone rainfall event in United States history, both in scope and peak rainfall amounts, since reliable records began around the 1880s.” Hurricane Irma was the second major hurricane to strike the continental U.S. coast in 2017, making landfall in the Florida Keys on September 10. Irma’s large wind field produced significant storm-surge flooding along the northeastern coast of Florida, even though the storm made landfall in southwestern Florida.
